Millions of people are affected by eye diseases which can affect the shape and dimensions of the whole eye.For examination of ocular accommodation and pathological changes caused by these diseases,high resolution imaging of the whole eye segments OCT system is desired.However,limited by the imaging depth,traditional Fourier Domain Optical Coherence Tomography (FD-OCT)can’t be used for real time whole eye segment imaging.In recent years,techniques for depth extended FD-OCT system especially for whole eye segment imaging has been developed.Application on eye parameters measurement and eye accommodation studies were successfully performed.In this paper,both of whole eye FD-OCT techniques and the application were reviewed.Potential clinical application of these techniques may be in the detection of the pathological changes of the whole eye,and whole eye segment FD-OCT system also provides a powerful imaging method for ophthalmic research.
